狗针麻胃大部切除手术实验模型

<正> 五年来(1975～1979) 的临床实践和实验研究证明,按胃大部切除手术过程中经常出现的症状辨证循经选穴,能够充分发挥针刺的调整作用,从而促使人体内发生一系例的规律性变化,并明显地提高了胃大部切除术的针麻效果。为了深入研究体内这些变化的发生机理,需要有一个近似针麻手术病人变化的实验动物模型。为此研制了本实验模型.

AN EXPERIMENTAL MODEL OF SUBTOTAL GASTRECTOMY IN DOGS UNDER ACUPUNCTURE ANESTHESIA

Subtotal gastrectomy was performed on 107 dogs,93 of which were operated under acupunctureanesthesia.The needling points were Xinshu,Neiguan,Pishu,Zusanli.The acupuncture anesthetic ef-fect was graded as:Excellent(Ⅰ),good(Ⅱ),poor(Ⅲ)and non(Ⅳ).In these 93 dogs,theanesthetic effect was excellent in 50(54%),good in 27(29%)and poor in 16(17%).During incision of the skin and peritonium,clamping gastric arteries(after 0. 5% procain 0. 2-0. 5ml infiltration),retracting the stomach,clamping and cutting the duodenum and the stomach,aswell as during gastro-intestinal anastomosis,there was no response in grade Ⅰ;in grade Ⅱ,the respon-ses to pain and visceral tractional sensation were slight and short;in grade Ⅲ there were marked andprolonged responses.On 12 dogs subtotal gastrectomy was performed without acupuncture but only with supplementarydrugs.All of these dogs struggled and barked during the whole operation.As for the dogs operated with neither acupuncture nor supplementary drags,the operation wasvery difficult to perform.At the end of the operation traumatic shock occured.This exprimental model not only can be used to prove the anesthetic effect of acupuncture butcan also be used to further the study of the mechanism of acupuncture anesthesia.
